Configuring port KHI

Use this procedure to configure port KHI.
Port KHI tracks the following information:
• Overall system statistics (unicast, multicast and broadcast Rx, Tx packets) for the
preceding two minutes
• Port up/down events
• SMLT port up/down events
• IST port up/down events
• Port errors
It also provides a history of the last 10 port KHI events.
The current up/down ports list is collected when you execute the show command. The system
statistics under port KHI are collected every two minutes and indicate the total packets (unicast/
multicast/broadcast) received/transmitted within the previous two minutes. When a clear
operation is performed, the operationally UP ports are stored as a reference, and the current
status for port KHI is marked as yellow if any of those ports go down.
The first time a particular port error occurs, it is reported as a KHI warning message and also
logged under the port KHI historical data. All subsequent port errors of the same type and on
the same port are not reported until a clear operation is performed.
To ensure the validity of the KHI information, ensure that it is in sync with the output from the
port show commands, and verify that the timestamps are relevant. There may be a slight delay
in the KHI output if shown concurrently with port show commands, as KHI polls line cards
consecutively, which can introduce a delay in the output for the first cards polled.
While the memory used for port KHI is minimal, collecting system statistics when a system is
busy can have a system impact.
Avaya recommends you enable port KHI when a system stabilizes.
